RICHARD SGHERL, OF ERLIN, GERMANY.

SUPPORT FOR MONOTRACK-VEHIGLES.

Specification of Letters Patent.

Patented Sept. l; 1908.

Application filed May 21, 1908. Serial No. 434;,071.

'known manner on a single rai The lateral supporting wheels come to rest accordin to this invention, when the vehicle is stan( ing still or traveling slowly, on auxiliary rails arranged at both sides of the track or of the main rail, while during normal driving, they are lifted oil' from them by means of a ccntri'fugal device. The supporting wheels are intended to become operative when the speed of the vehicle fais below a certain' limit, for as is well known a single track vehicle can remainv vertical only at a certain speed, while, when the speed descends below the said limit, it is liable to turn over. lhe device for generating power for raising and lowering the lateral su porting wheels, for instance, a centrifugal) governor, can therefore be connected to the driving device of the vehicle in such manner that when the minimum speed required for maintaining the oi' a inonorail railway is marked d. The carriage is normally,supported by the Vmain or road wheels '(L which can also be combined into bogies. At both sides oi the carriage are adjustably arranged the supporting wheels b and c. The raising of the oblique supporting wheels can be ell'ected both in oblique and in vertically arranged guides.

Vthe rotating masses f move in and out in a plane at a right angle to the axis g ofthe governor, the sleeve h of the governor, connected by rods l to the adjustable bearings lc of the supporting'wheels a, bringing about the raising of the said wheels at a given speed of ro'-- tation ofthe governor. 0f course the transmission of movement of the governor to the supporting wheels lcould also be' effected in some other simplemanner, for instance, by means of a rope, chain or similar parts (Z, Fig. 2). The supporting wheels, in order to enable the smallest forces of the sleeve of the overnor to be utilized, could be suitably A alanced.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a device for raising and lowering supporting wheels in a monotrack vehicle the combination oi' central wheels, supporting wheels laterally arranged on the vehicle, means for lifting the lateral Wheels when the vehicle is running at normal speed and for automatically lowering the said wheels when the vehicle slows down or stops so that the vehicle normally runs on the central wheels only.

' 2. In a device for raising and lowering supporting wheels-in a monotrack vehicle t e combination of central wheels, supporting wheels laterally arranged on the vehicle, a centrifugal governor to lift the lateral wheels when the vehicle is running at normal s eed and automatically to lower the said Wieels when the vehicle slows down or stops so that the vehicle. normally runs on the central wheels only.

Ain witness whereof l have hereunto signed my naine this Sth day of May 1908 in the presence of two subscribing witnesses.
